GENERAL INFORMATION Journey' herbicide is an aqueous solution to be mixed with water and an adjuvant and applied as a spray solution to provide weed control and/or turf height suppression on pastures, rangeland (see Guidelines For Rangeland Use section), Conservation Reserve Program (CRP) land and specified noncropland areas that may be grazed or cut for hay. Noncropland areas that may be treated are railroad, utility, pipeline and highway rights -of -way, railroad cross- ings, nonagricultural fence rows, non - irrigation ditchbanks, prairie sites, airports, non - residential turf and industrial noncropland areas such as utility plant sites, petroleum tank farms, pumping installations, storage areas and industrial turf. Journey may be used for the release of unimproved common Bermudagrass, vegetation manage- ment prior to the establishment of certain native prairiegrasses, (orbs, other grasses, desirable brush species and wildflowers (see appropriate sections) and for wildlife habitat management. Journey is readily absorbed through leaves, stems, and roots and is translocated rapidly throughout the plant, with accumulation in the meristematic regions. Treated plants stop growing soon after spray application. Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground storage organs, which pre- vents regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species for several weeks after application. Complete kill of plants may not occur for sev- eral weeks after application. Adequate soil moisture is important for optimum Journey activity. When adequate soil moisture is present, Journey will provide residual con- trol of susceptible germinating weeds. Activity on estab- lished weeds will depend on the weed species and rooting depth. Journey is rainfast one hour after application. Journey will control annual and perennial grasses and broadleaf weeds and vine species. Journey will provide residual control of labeled weeds which germinate in the treated area. Certain brush species and ornamentals may be injured by direct application of Journey to their foliage. This product may be applied either preemergence or postemergence to the weeds; however, postemergence application is the method of choice in most situations, par- ticularly for perennial species. For maximum activity, weeds should be growing vigorously at the time of posterner- gence applications, and the spray solution should include an adjuvant (See Adjuvants section). These solutions may be applied as a broadcast or as a spot treatment using backpack or ground equipment. Journey may be applied in the dormant or growing sea- son for weed control. Some yellowing of unimproved common Bermudagrass turf may occur with applications during the growing sea- son. Depending on weather conditions, yellowing will usu- ally disappear in 2 to 4 weeks. Journey should not be applied to newly seeded or sprigged grass stands, but may be applied prior to new seeding of certain species. MANAGING OFF - TARGET MOVEMENT Spray Drift: Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment- and weather - related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions, Spray drift from applying this product may result in dam- age to sensitive plants adjacent to the treatment area. Only apply this product when the potential for drift to these and other adjacent sensitive areas (e.g. residential areas, bod- ies of water, known habitat for threatened or endangered species, or nontarget crops) is minimal. DO NOT apply when the following conditions exist that increase the likeli- hood of spray drift from intended targets: high or gusty winds, high temperatures, low hurnidity or temperature inversions. To minimize spray drift, the applicator should be familiar with and take into account the following drift reduction advisory information. Additional information may be avail- able from state enforcement agencies or the Cooperative Extension on the application of this product. The best drift management strategy and most effective way to reduce drift potential is to apply large droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential but will not prevent drift if applications are made improperly or under unfavorable environmental conditions (see Wind, Temperature and Humidity and Temperature Inversions). Controlling Droplet Size: • Volume - Use high flow rate nozzles to apply the high- est practical spray volume. Nozzles with higher rated flows produce larger droplets. • Pressure - DO NOT exceed the nozzle manufacturer's recommended pressures. For many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure. • Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage. • Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream produces larg- er droplets than other orientations and is recommended practice. Significant deflection from the horizontal will reduce droplet size and increase drift potential. • Nozzle Type - Use a nozzle type that is designed for the intended application. With rnost nozzle types, nar- rower spray angles produce larger droplets. Consider using low -drift nozzles. Solid- stream nozzles oriented straight back produce the largest droplets and the low- est drift. DO NOT use nozzles producing a mist droplet spray. 40 1 0 i
